My friend Dave Dugdale with www.learningdslrvideo.com has just released his video training on the Canon T3i (he also already has one for the T4i).
While my Canon Crash Courses
give a robust introduction to photography and an introduction to video shooting, Dave's lessons are primarily focused on video and he is the first and only other instructor I recommend when it comes to the technical shooting aspects of video. He gets in to some very specific details and has done a lot of research so you do not have to., If you own a T3i or T4i and want to get the most out of your video footage, it is definitely worth the investment:
